Results for the four dusty star forming galaxies of Sect. 4.2.1 Upper panels: GalaPy fits to the photometric data of four galaxies selected from the Pantoni et al. (2021) sample (blue markers with error-bars). Best-fitting model (black solid line), different components (colour-coded as in legend), and 1- and 2-σ confidence levels (grey shaded regions) around the mean of the samples are also shown. Lower panels: Standardised residuals with respect to the best-fitting galaxy models, and 1-/2-σ confidence intervals around the mean of the samples (grey shaded regions) are shown; the reduced χ² of the fit is reported in each sub-panel.
